Vibro Sieve -DAHAN Vibration Machinery

Introduction of Vibro Sieve

Vibro sieve, also called vibro sieve separator, vibro sieve shaker, it screens products by using a customized layered screen and 3D motion, it can be used to screen dry powder or granular products as well as wet products and liquids, it can eliminate foreign matter in the product With continuous filtration, up to 5 levels of product separation can be performed in just 1 operation.

Vibro sieve can screen up to 500 mesh and comes in a variety of sizes (from 400mm to 2000mm) to meet the screening needs of different industries. The output ranges from 100 to 3300kg/h. It is widely used in food and beverage, pharmaceutical, paper and pulp, and metal powder. , powder coatings and other industries, and can be fully customized to your application.

Function of Vibro Sieve

The main function of Vibro sieve is to separate and classify particles according to their size and shape. The following are the main functions of vibrating screens:

1. Safety screening: Usually used for safety screening to remove any oversized or foreign particles in the material. This ensures the quality and purity of the final product and prevents any potential contamination.

2. Classification: The main function of the vibrating screen is to separate particles according to their size. The vibrating motion of the screen moves the particles across the screen surface, allowing smaller particles to pass while larger particles are retained. This separation process helps achieve the desired particle size distribution. The sieve creates multiple layers of particle separation, allowing precise sorting based on particle size.

3. Solid-liquid separation: The process of separating solid particles from liquids in a mixture. This separation process is very common in many industries such as chemicals, food processing, pharmaceuticals, etc.

4. Dehydration: In some applications, vibrating screens are used to remove excess moisture from the particles. The vibration of the screen aids drainage and dewatering of particles, thereby improving particle handling and downstream processes.

Types of Vibro Sieve

There are several types of vibro sieves available, each designed for specific applications and particle separation requirements. Here are some common types of vibro sieves:

Type	Normal type	Ultrasonic type	Direct discharge type	High frequency type
Type
Features	Utilizes simple adjustment of counterweights on the motor shaft and the three-dimensional vibration they generate to screen material, can be used to remove broken or undersized products, and can provide up to 5 levels of classification in one operation to achieve the best particle size distribution	The ultrasonic system is used to apply high-frequency vibration to the screen. The frequency of vibration breaks the surface tension, making the stainless steel mesh effectively friction-free and preventing particles that are too large and too small from clogging or clogging the screen. It can be used in finer meshes (low to 20 microns).	The inlet and outlet are designed in the same vertical direction. The large flow outlet at the bottom allows materials to be discharged directly. The discharge speed is fast. The output is 2-5 times that of ordinary round screens. It can be directly used in series in pipelines to remove foreign matter and impurities in pipelines.	A 2-stage motor is used as the excitation source, which makes the vibration intensity reach 2-3 times that of ordinary vibrating screens, which can quickly destroy the surface tension of viscous slurries entering the screen, thereby reducing their residence time on the screen and achieving rapid filter.
Mesh size	500	625	140	400
Capacity	100-5000	100-5000	3000-30000	400-1200
Application	For batch grading or safety screening of powders and liquids.	Suitable for ultra-fine powder with strong adsorption, viscosity, high static electricity and high density.	Ideal for screening incoming ingredients and final production inspection of finished products	Used for filtering and removing impurities from viscous slurries, such as ceramic slurries, paints, coatings, etc.

Working Principle of Vibro Sieve

Vibro sieve is mainly composed of a vibrating motor, a screen, a cleaning device, a net frame, a shock-absorbing spring, a base and other parts. After the stainless steel rotary vibrating screen is started, the motor drives the heavy hammer to vibrate, and the screen body produces horizontal, vertical, and inclined The three-dimensional movement causes the material to be thrown up on the screen and rotate outward from the center to the discharge port to be discharged. When the material moves on the screen, fine particles or liquids pass through the screen, and the corresponding screen is installed by selecting And the number of screen layers enable the materials to be screened, classified or filtered, and the sorted materials are automatically discharged from their respective outlets.

Benefits of Vibro Sieve

High efficiency

The vibration of the screen helps to effectively separate the solid particles from the liquid, making the separation process more efficient and faster compared to other methods.

Precise particle size control

By adjusting the amplitude and frequency of vibration, the sieve can achieve precise separation and classification of particles according to their size.

Versatility

Can handle a variety of materials and applications. They can be used in a variety of solid-liquid separation processes, including particle separation, classification, classification, dehydration, dust removal and safety screening.

High throughput

All feed materials are automatically discharged, and there is no material stored in the machine. The screen surface and screen surface have a larger capacity than other types of screen surface machines, and the processing capacity can reach 100-3300kg per hour.

Multi-level classification

You can choose to install 1-5 layers of screens, which can sort or filter 2-6 products of different specifications at the same time.

Not easy to block

A bouncing ball cleaning device is installed under the screen, which can smoothly discharge materials adhered to the mesh by hitting the screen.

Structure of Vibro Sieve

1. Screen frame: The screen frame is the main structure of the vibrating screen. It is usually made of steel or other strong material and provides stability and support to the screen assembly.

2. Screen surface: The screen surface is the area where particle separation occurs. It is usually a screen or cloth made of materials such as stainless steel, nylon or polyurethane.

3. Vibration system: The vibration system is responsible for generating the vibration motion of the screen. It usually consists of an electric motor or an eccentric weight system.

3. Support spring or suspension: In order to ensure correct vibration transmission and minimize excessive vibration, the vibrating screen is equipped with a support spring or suspension system.

4. Drive unit: The drive unit provides power for the vibration system, usually an electric motor.

5. Discharge port: The discharge port is the opening through which the separated particles leave the vibrating screen.
